“…While national measurements such as the NIS can identify variations in rates between states, state-level programs have been left on their own to identify what in-state factors are affecting their rates [6]. Also because immunization levels are often taken as a measure for overall quality of care in early childhood [1], counting doses by age two is not as strong a proxy as is the checking of timely receipt of age-appropriate immunizations across the entire period from birth to age two.…”

“…The growing complexity of the early childhood immunization schedule, with up to 19 vaccine doses recommended across at least 6 visits by age 2, means that there are many points of time and many reasons by which children can fall behind on immunizations [5]. While immunization summary UTD rates for 2-year-olds can identify general problems, there is also a need for more detailed assessment tools to describe local immunization coverage and more specific vaccine usage [6]. …”

A challenge facing immunization registries is developing measures of childhood immunization coverage that contain more information for setting policy than present vaccine series up-to-date (UTD) rates. This study combined milestone analysis with provider encounter data to determine when children either do not receive indicated immunizations during medical encounters or fail to visit providers. Milestone analysis measures immunization status at key times between birth and age 2, when recommended immunizations first become late. The immunization status of a large population of children in the Oregon ALERT immunization registry and in the Oregon Health Plan was tracked across milestone ages. Findings indicate that the majority of children went back and forth with regard to having complete age-appropriate immunizations over time. We also found that immunization UTD rates when used alone are biased towards relating non-UTD status to a lack of visits to providers, instead of to provider visits on which recommended immunizations are not given.

“…Starting in 2006, the NIS conducted national surveys to determine adolescent vaccine rates and is the only national survey to estimate adolescent vaccination coverage. 7 The NIS data are useful in determining overall trends of adolescent vaccine uptake, but there are limitations to the data. It takes a year to collect the target sample size per area and, as a result, NIS data are reported for the previous year, leaving a gap between changes in the vaccination schedule and evaluation by NIS.…”

Objectives. We described the uptake and coverage rates of meningococcal conjugate vaccine (MCV4); tetanus-diphtheria-acellular pertussis vaccine (Tdap); and quadrivalent human papillomavirus vaccine (HPV4) in North Dakota using the North Dakota Immunization Information System (NDIIS).Methods. We analyzed all available MCV4, Tdap, and HPV4 doses given after vaccine licensure and through December 31, 2009, obtained from the NDIIS to identify trends and patterns in vaccine administration. We analyzed all data by administration date, age group, and health-care provider type. We also calculated missed opportunities to complete all recommended vaccines among vaccinated adolescents.Results. For adolescents aged 13-17 years, 69.2% had $1 dose of Tdap and 62.8% had $1 dose of MCV4. Of females aged 13-17 years, 42.8% initiated the HPV4 vaccination series and 24.9% received $3 HPV4 doses. Only 48.7% of males aged 13-17 years received both Tdap and MCV4 at the same visit, and only 11.5% of females aged 13-17 years received Tdap, MCV4, and HPV4 doses at the first visit.Conclusions. The NDIIS is useful in tracking adolescent vaccine uptake. The immunization rates for all three routinely recommended adolescent vaccines are rising in North Dakota, although at different paces. Providers should be educated about the importance of not missing opportunities to vaccinate, and school-based vaccination clinics should be used to reach adolescents who are less likely to have preventive care visits.

Assessing vaccination coverage is of paramount importance for improving quality and effectiveness of vaccination programs. In this article, some of the different systems that are used for assessing vaccination coverage within and outside the EU are reviewed in order to explore the need for improving vaccination coverage data quality. All countries in the EU have implemented vaccination programs for children, which include vaccinations to protect against between nine and 14 infectious diseases. Collecting and assessing vaccination coverage regularly is part of such programs, but the methods used vary widely. Some quality issues are evident when data reported through administrative methods are compared with seroprevalence studies or other surveys. More thorough assessment of vaccination coverage and more effective information sharing are needed in the EU. A homogeneous system for assessing vaccination coverage would facilitate comparability across countries and might increase the level of the quality of both the national and local systems. Cooperative and coordinated responses to vaccine-preventable disease threats might be improved by better information sharing.
